英文摘要	Silicon-promoted K2WO4/Al2O3 catalysts for methanethiol synthesis from methanol and H2S were prepared and characterized by XRD, in situ pyridine adsorption FT-IR and NH 3/CO2-TPD, etc. techniques. With increasing the amount of Si added, the crystallite sizes of the catalysts decreased, while the surface area increased at first and then decreased. When the content of Si in the catalyst increased in the range from 1 to 5%, the acidity of the catalyst increased, while the basicity decreased. The highest catalytic activity of the catalyst for the reaction can be obtained when Si content in the catalyst is as high as 5%. 漏 2012 Elsevier B.V. All rights reserved.
